I have a question for ya’ll.
When setting up the main and jib sheeting, do the booms travel together, remaining parallel to each other?
What are you getting at, Nigel? Anything fancy? 
Nah, just setting up me rig.
The length of line required for both booms, differs from one another.
So, i’m mucking with things to pull the two different lengths, with the one swoop of the servo.
Wondering what the norms were.
That’s easy.
Get yourself some rubber grommets that fit the booms snugly, and tie some string or wire loops to them. The sheets clip to the loops, and you move the grommets back & forth to get the desired boom travel.
figured out similar.
thanks though.
